Detailed Description

template<typename ZipOp, typename ReduceOp, typename View>
struct stapl::skeletons::skeletons_impl::hand_execute_impl< stapl::skeletons::skeletons_impl::zip_reduce< 1, ZipOp, ReduceOp >, View >

Execute a zip_reduce with one view in place.

This implementation requires that identity_value is defined for the reduction operator. This is for two reasons: 1. This method is SPMD and thus there needs to be a way to incorporate an empty location's result without affecting the globally reduced value. 2. It is not clear how to have a preamble that only applies the zip operator to the first element, and then skips the first element for the main loop, since there are nested loops.

Template Parameters

ZipOp	The zip operator of the skeleton
ReduceOp	The reduction operator of the skeleton
View	The single view to use as the source of data
